What up everyone!!! Roookie over here trying to find the best way to go high horse power with the 2.7T engine that i plan on putting together while my 1.8t aeb blows each of the four pistons out the hood but idk when that will be because i only have 130K miles on it i chipped it Ko4 in it 5bar fuel regulator tiny gap in sparkplugs no cat 3" pipe alllllllll the way to the back and not to brag but i got it to back fire lol and i like push it to the max everyday and the engine is in like a 5/10 apearance but it still holds it you kno
And i want to start building a 2.7t in my garage while this one blows out and first goal is to beat my 2008 bmw M3 lol second goal is to reach 800+ bhp i have done some research and found pretty cool gt40r turbos for it but i want to know which of the 2.7t engines is the best for that and just kinda get some guidence from you Pros out there and switching car or getting rid of it to buy something better is not an option i want to build my dream car even tho it sucks and im already getting headaches with this 200hp 1.8t engine
